Quick facts

The massive Tunnel Boring Machines on the Airport Link project in Brisbane have a cutter head with a diameter of 12.48 metres, are 195 metres long and weigh a huge 3,600 tonnes each - the equivalent of 75 semi-trailers.
At the Burton coal mine in Queensland, Thiess has taken delivery of the world’s largest mining backhoe excavator, which has a bucket larger than many Australian living rooms and is capable of lifting 75 metric tonnes.
The Leighton Group operates in more than 20 countries and has more than 42,000 direct employees.
In 2009, the Leighton Group mined over 100m tonnes of coal, more than 100m tonnes of iron ore and moved around 920m bank cubic metres of overburden. This equates to the movement of more than 2bn tonnes of material or digging a 1km deep hole stretching 1km wide by 1km across.
At the Mt Owen coal mine in the Hunter Valley, Thiess are mining 8.2m tonnes of coal per year from pits as deep as 270m. That’s nearly deep enough to bury the Eiffel Tower.
At the Victorian Desalination plant, Thiess are delivering the largest desalination plant in Australia, capable of supplying up to 150 billion litres of water a year - a third of Melbourne's annual water needs.
The Capital Gate building in Abu Dhabi, currently under construction by the Al Habtoor Leighton Group, has been certified as the ‘World’s Furthest Leaning Manmade Tower,’ by Guinness World Records. The 160-metre, 35-storey tower has been built to lean 18 degrees westwards - more than four times that of the world famous Leaning Tower of Pisa.
